The qed utility is a fullscreen editor that's been
shipped with QNX since the early days of the QNX 2 operating system.
It has been ported to QNX Neutrino for the convenience of the many people who
have become accustomed to it. However, it's no longer the preferred
editor in QNX Neutrino and its use is deprecated. The qed
editor is available only on the QNX OS, while other editors such as
vi
and emacs are more universally available.

If you enter this editor by accident, the best way to get out is
to press qEnter while the cursor is on the top
command line. Because it was designed for the console with full
PC keyboard capabilities, its use is more limited on terminals and
many terminfo entries don't describe the capabilities it requires
for such basic things as getting back to its command line.

For more information on qed, you'll find a
complete HTML manual
online.
